Multiple Imputation using Weighted Quantile Sum Regression

The `miWQS` package handles the uncertainty due to below the detection limit in a correlated component mixture problem. Researchers want to determine if a set/mixture of continuous and correlated components/chemicals is associated with an outcome and if so, which components are important in that mixture. These components share a common outcome but are interval-censored between zero and low thresholds, or detection limits, that may be different across the components. The `miWQS` package applies the multiple imputation (MI) procedure to the weighted quantile sum regression (WQS) methodology for continuous, binary, or count outcomes. The two imputation models coded in `miWQS` package are: bootstrapping imputation (Lubin et.al (2004) ) and Bayesian imputation.


News

miWQS 0.0.9

*First Release of Package to the public. *For updates to CRAN team, see cran-comments.

  • Replaced examples using example dataset in package instead of using package wqs. Looks cleaner
  • Remove printed output from estimate.wqs.
  • Made documentation from estimate.wqs clearer.
  • Cleaned up print.wqs documentation

miWQS 0.0.8

  • Reworked plot.wqs() function by using ggplot2 instead of base plotting in R.

miWQS 0.0.7

  • Fixed bug in doing Poisson Rate WQS regressions. Added argument offset to the check_function() and randomize.train()
  • For updates to CRAN team, see cran-comments.

miWQS 0.0.0
